Deficits in quadriceps strength of the injured leg have been observed in patients following anterior cruciate ligament (ACL) reconstructions and may contribute to ACL re-injury risk. Single-leg forward hopping is a widely used task for assessing knee function in patients following ACL reconstructions as it has been shown not to be particularly challenging to the knee. This study aimed to quantify the effect of decreased quadriceps strength induced by a fatigue protocol on hopping performance and lower limb mechanics in single-leg forward, vertical, and backward hopping.

向后跳跃以向前移动：与向前和垂直跳跃相比，单腿向后跳跃可以更好地检测疲劳方案引起的股四头肌力量下降


在前交叉韧带 （ACL） 重建后的患者中观察到受伤腿股四头肌力量的缺陷，并可能导致 ACL 再损伤风险。单腿前跳是一项广泛使用的任务，用于评估 ACL 重建后患者的膝关节功能，因为它已被证明对膝关节没有特别的挑战性。本研究旨在量化疲劳方案引起的股四头肌力量下降对单腿向前、垂直和向后跳跃的跳跃性能和下肢力学的影响。
